小编use*_*641的帖子

1. 我正在运行以下命令,以便在该文件" pip install -r requirements.txt --download-cache=~/tmp/pip-cache"中安装软件包 .

2. requirement.txt包含像pacakages

# Data formats

PIL==1.1.7 # 

html5lib==0.90
httplib2==0.7.4
lxml==2.3.1

mock==0.7.2
testscenarios==0.2
testtools==0.9.14
wsgi_intercept==0.5.1

当我想要安装"lxml"软件包时,我得到了以下的错误

Requirement already satisfied (use --upgrade to upgrade): django-testproject>=0.1.1 in /usr/lib/python2.7/site-packages/django_testproject-0.1.1-py2.7.egg (from django-testscenarios==0.7.2->-r requirements.txt (line 33))

views.py

if 'send_email' in request.POST:
    subject, from_email, to = 'Parent Incident Notification',user.email, person.parent_email
    html_content = render_to_string('incident/print.html',{'person':person,
                                                                 'report':report,
                                                                  }) 
    text_content = strip_tags(html_content) 
    msg = EmailMultiAlternatives(subject, text_content, settings.DEFAULT_FROM_EMAIL, [to])
    msg.attach_alternative(html_content, "text/html")
    msg.send()

以上是发送电子邮件的视图.通过这种方式,我可以发送html内容和邮件,它发送电子邮件到[地址]单独,我想制作另一个密件抄送和cc也.我经历了Emailmessage objects 在文档中.我不知道如何包含bcc和cc来改变我的观点.

需要帮忙.

谢谢

settings.py

EMAIL_BACKEND = 'django.core.mail.backends.console.EmailBackend' 
EMAIL_USE_TLS = True 
EMAIL_HOST = 'smtp.gmail.com' 
EMAIL_PORT = 587 
EMAIL_HOST_USER = 'rakil@gmail.com' 
EMAIL_HOST_PASSWORD = '*******' 
DEFAULT_FROM_EMAIL = 'testing@testing.com

但邮件没有发送到地址,在print.html我点击send_email时打印机正在打印,但是它没有发送任何电子邮件.我正在使用Django 1.3.7和Python 2.6.

我不知道问题是版本还是一些逻辑问题.需要帮忙.

forms.py

Date_Format = (
    ('0', ' dd / mm / yyyy'),
    ('1', 'mm / dd / yyyy'),
)    
Time_Format = (
    ('0', ' 12 hour AM / PM '),
    ('1', ' 24 hour '),
)
class SettingsForm(forms.ModelForm):
    date_format = forms.ChoiceField(widget=forms.RadioSelect(), choices=Date_Format)
    time_format = forms.ChoiceField(widget=forms.RadioSelect(), choices=Time_Format)

template.py

更新:

                    {% for radio in SettingsForm.date_format %}
                    {{ radio.choice_label }}
                    <div class="select">{{ radio.tag }}</div>
                    {% endfor %}

上面的表单将单选按钮呈现在无序列表中,但我希望无序列表.我怎么能这样做？

models.py是

from django.db import models

    class Book(models.Model):

        book_id=models.AutoField(primary_key=True,unique=True)
        book_name=models.CharField(max_length=30)
        author_name=models.CharField(max_length=30)
        publisher_name=models.CharField(max_length=40)

        class Meta:
            db_table = u'Book'

        def __unicode__(self):
            return "%d %s %s %s" % (self.book_id,self.book_name, self.author_name,self.publisher_name)

forms.py是

from django import forms
from django.forms import ModelForm
from myapp.models import Book


class BookForm(ModelForm):

    class Meta:
        model = Book

        fields=['book_id','book_name','author_name','publisher_name']

我的views.py是

def editbook(request,book_id):

    queryset = Book.objects.filter(book_id=book_id)
    if request.POST:
        form=BookForm(request.POST,instance=queryset)
        if form.is_valid():
            form.save()
            return redirect('index')
    else:
        form=BookForm(instance=queryset)
        template = 'editbook.html'
        book = { 'form':form }
    return render_to_response(template, book , RequestContext(request)) 

我需要编辑和更新数据库中已存在的数据行.我猜他们在views.py中存在一些问题.所以我不确定我的views.py是对的.请检查并告诉我是否有任何问题以及如何继续.

谢谢

的index.html

<td>{% if place or other_place or place_description%}{{ place}} {{ other_place}} {{place_description}}</td>

这是在模板中显示所有数据.如果字符串长度超过80,我想截断它.

条件是,1.如果地方变量有超过80个字符,它应截断它们,不需要显示另外两个变量,如other_place和place_description.

2.如果放置变量和other_place变量超过80个字符,在这种情况下它应该从place_variable截断不需要显示place_description变量.

3.如果所有这三个都是他们的,而第80个字符是由place_description制作的,则需要截断他们的.

所有字段都不是必填字段,因此无论显示哪个字段,它都应该只显示80个字符.

需要帮助才能做到这一点.

谢谢

我想使用jQueryUI对话框在我的Django项目中添加一个功能,当你点击链接(如"删除"链接)时,会弹出一个jQueryUI对话框,询问你是否真的要删除该项.然后,如果单击删除按钮(找到jQuery对话框),Django函数将执行删除作业.

那么如何使删除按钮(找到jQuery对话框)发送一条帖子消息(带有相应的变量)到我的views.py中的Django函数,它将执行删除作业？

考虑我正在使用view.py文件(在Django中),如下所示

def deletebook(request,book_id):
    books=Book.objects.get(pk=book_id)
    books.delete()
    return redirect('/index/')

我的要求是如果我按下删除选项,立即出现一个确认对话框,其中包含2个字段,如下所示"是"或"否".

请帮我设计一个html页面和一个用jQuery开发的view.py页面.

我的HTML页面是

<form action="/deletebook/{{ books.book_id}}/" method="POST"> {% csrf_token %}
<table>
  <tr>
    <td align="right">Book Name :<br><br><br> </td> 
    <td align="left"><input type="text" name="book_name" value="{{books.book_name}}"></input><br><br><br></td>
  </tr>
  <tr>   
    <td align="right">Author Name :<br><br><br></td> 
    <td align="left"> <input type="text" name="author_name" value="{{books.author_name}}"></input><br><br><br></td>
  </tr>
  <tr>
    <td align="right">Publisher Name : <br><br><br></td>
    <td align="left"><input type="text" name="publisher_name" value="{{books.publisher_name}}"></input><br><br><br></td><br><br><br>
  </tr>
</table>
<td><input type="submit" value="Delete"><td> 
</form>

forms.py

class ImportExcelForm(Form):
    file  = forms.FileField(attrs={'class':'rounded_list',})

我正在尝试将css类添加到我filefield的表单中.我收到此错误"__init__() got an unexpected keyword argument 'attrs'"

我做错了什么.

谢谢

forms.py

DATE_INPUT_FORMAT = (
    ('%d/%m/%Y','%m/%d/%Y')
)

class ReportForm(forms.ModelForm):
    manual_date = forms.DateField(input_formats = DATE_INPUT_FORMAT,
                      widget=forms.DateInput(format = '%d/%m/%Y'))  

1.Date格式应该根据数据库中的值进行更改,如果value在db中,则显示第一种格式,不显示,否则部分正在执行.

2.格式的变化取决于条件.

3.我在这里面临问题,如果输入格式为此(%m /%d /%Y),则在表单上,​​日期值将被交换并保存在数据库中.如果给定日期是07/06/2013 - > 2013年6月7日,在表格发布后,它将在2013年7月6日 - > 2013年7月6日在现场查看.它无法正常工作.

需要帮助来解决这个问题.

谢谢

在解析xml文件时,我得到以下回溯

ParseError at /addxml/
junk after document element: line 13, column 2
Request Method: POST
Request URL:    http://localhost:8000/addxml/
Django Version: 1.3.7

Exception Value:    
junk after document element: line 13, column 2
Exception Location: /root/Samples/DemoApp/DemoApp/views.py in addxml, line 98

这是我的代码

if request.POST:
        path = "{0}/app_name/filename.xml".format(settings.PROJECT_ROOT)
        xmlDoc = open(path, 'r')
        xmlDocData = xmlDoc.read()
        xmlDocTree = etree.XML(xmlDocData)

下面的行给出了错误

xmlDocTree = etree.XML(xmlDocData)
